Application June 4*,194s,seria1Nirs1,17c 1 This invention relates'to anonskid device such ts is adapted to be attached to an automobile tireto decrease slipping and spinning of. thejdrive wheelsof a vehicle.

An object of this invention is to provide a nonskid device, for avericle tire, constructed from .asingle continuous length of flexiblewire rope facture, .eicient in operation, easily applied, and4 which hasrelatively long life in use.

Another vobject is to .provide amethod .of .constructing a nonskiddevice, for a vehicle. tire,

from a single continuous length of flexible wire rope or cable.:.`.' x yp Further objects and advantages of this invention, as wellas itsconstruction, arrangement andoperation. will be apparent from the,following description and claims when. takenin vconnection with theaccompanying drawing, in which; i

' Figurev is a plan view of the and f Figures 4 and 'indicate the methodof interlacing the cablestrands of the. device at the crossovers, astaken on lines 4 4 and 5.5,'re spectively`,ofFigure 3.

In Figure 2is shown the method of constructing the device ofv thisinvention wherein vinitially there is provided a temporary base or boardI9 in whichvaresecured nails or pins II, I2, ,I3 and I4, to hold thecable frame to required dimensions. A continuous length of ilexiblesteel, bronze, or other suitable wire rope or cable I5 beginning at thecable'end rI6 istemporarily laid along' the base board I0, looped atpoint `I1 anda metal nisiied device,

ring I8 slipped over the cable and the cableendj then passed backthrough the ring to forman eye I9., ",Iheeye:` I9 is temporarily placed.over the pinfII; and loop4 20 similarly formed and eye. I9 placed'over.`pin 'I2gfor temporary'support until the frame portion of the device iscompleted.

The cable I5 is then continued in reverse ditaut andV secured to 3Claims- Kcl. 152-2215- rection on the'i base ID toward pin` I3`wh'e`reanother ring I8 is slipped over the 'cable' followed by the eye of asnap hook 2| andthe cable end passed'b'acl:` through the vring I8 toform eye 22. The snap hook 2l is then placed 'over the pin I3.Eye-"23.i's similarly formed and snap hook 211 placed 'over 'pin Ill.VThe `cable is then drawn theinitial endv IB -by means of .a double clamp25 forming a rectangular frame on which theftransverse members will b-esupported and secured;' 'i l j 1 Y At a' suitable ldistance beyond' theclamp 25 two strands I5a of the free end ofthe cable I5 may be unwound,the cable bent at right angles and the'two unwound strands insertedbetween two upraised strand'sof theframe at point 2G, as showninFig'ures 4 and A5, to secure and'form a transverse member 21.The,unwound strands may then be rewound i'n place and the operationrepeated' at each successive crossover pointl26, as shown in Figure 3,forming a series of trans- Verse members 21 suitably spaced throughoutthe length of the longitudinal sides of the frame. Between theCrossovers 26 the free end of the cable may be looped at I5b around thelongitudinal frame members as shown to impart` the desired support tothetransverse members. When all of the transverse members 21 have beenthus provided the remaining reeend of the cable may` then be securedltothe longitudinal vframe member by means of a double clamp 28. y

The completed deviceV is then removed from the pins II, I2, I3 and I4',andis ready to be applied to" avpneumatic tire 30 (Figure 1) by placingit around the tire, as shown in Figure l, and securing in place byinserting snap hooks 2l and 24 in the eyes I9 and I9, respectively, ofthe opposite end of the frame. v

If desirablethe exposed portions of the transverse members or crosspieces 21 may be given a coat of hot spelter to protect them againstexcessive abrasive wear and the-Wire rope and ttings may be galvanizedto prevent undue corrosion.

It will be readily .understood that when in operation this devicewillproduce a minimum of noise, wear, breakage and resulting damage to thevehicle such as often occurs when chain links, of which similar devicesare made, break and that the surface of the tire and the `roadway onwhich this device may be used will suffer less wear and damage than whensimilar devices constructed of solid metal links andthevlikeare It is tobe understood that various modications n and change's'may be made inthis invention Without departing from the spirit and scope thereof, asset forth in the appended claims.
